Description
Technical field
The present invention relates to lens and a kind of according to claim 7 lens family of preamble of a kind of method for the manufacture of lens of preamble according to claim 1, a kind of preamble according to claim 4.
Background technology
According to 2760 the researchs that people carry out of age between 20 to 45 years old that utilize in France, the U.S. and Japan, it is said that 60% population is subject to the puzzlement of eye fatigue.The people's of experience eye fatigue eyes no longer can be focused best and the ability of its focusing goes down.This causes the dimness of vision and tired discomfort.This tired discomfort especially occurs in pressure, artificial light, the situation such as work long hours before computing machine.This discomfort be closely more and more stronger and lasting long period with due to eye.
Different lens manufacturer has realized that this problem and the lens of particular design is provided for non-presbyopic crowd.Essilor company provides its myopia part (Nahteil) to have+lens that the effect of 0.60D increases with respect to zero degree eyeglass or conventional single vision lenses under trade mark " AntiFatigue ".The near-sighted partial action of this raising works in the mode of support regulating, so that the adjusting pressure when being reduced in nearby visual task.This lens is described in 610 B2 to some extent also at US 7,540.It is also known that, arrange to assemble with the form of the prismatic action that improved in myopia part and support, the convergence pressure when being reduced in visual task nearby.The combination that is made of two kinds of supporting steps is also possible.
Although this or other the lens that reduces vision pressure is proved to be basically as effectively, show, the non-presbyopic people who wears greatly the glasses of the lens with aforementioned reduction vision pressure still complains eye fatigue.
Summary of the invention
Therefore task of the present invention is, a kind of method for the manufacture of lens is provided, and utilizes the method to make to have the lens of the further improvement of the effect that reduces visual fatigue.Should provide a kind of lens of the improvement be used to reducing vision pressure in addition.
The method of the feature of this task by having claim 1 and have the lens of feature of claim 4 and the lens family with feature of claim 7 solves.Favourable enforcement of the present invention and stretching, extension explanation in the dependent claims.
The present invention has realized that, it is said that the reason that reduces the incompatibility that lens vision pressure or the prevention eye fatigue partly is discontented with by non-aging eye crowd is, all effects that are designed to reduce near-sighted pressure of the myopia part of obtainable lens so far are given in advance regularly according to unified mode, and do not design according to non-presbyopic people's independent demand.In the design of both size and the profile of the size and shape of lens, especially picture frame not having be considered lens on the one hand, usually do not use the service condition of glasses to consider in the design of lens non-presbyopic people, namely the geometric shape of lens yet.
Should be noted that concept " lens " is not only to be understood to solid material unbodied, amorphous under traditional sense, but also be interpreted as being arranged for the glasses part of perspective.Presbyopic people is such people, and it partly or even fully loses the near-sighted matching capacity by means of the eyes of regulating usually due to the age, so clear vision on hand is not in the situation that have suitable rectification no longer can not have to carry out uncomfortablely.Therefore it is not enough that non-presbyopic people does not have or only have slight adjusting.Can not get rid of the visual impairment that this non-presbyopic people has other form.Especially can enjoin correcting spherical and/or astigmatism to such people by optist or oculist.Also possible is to enjoin the prism rectification with the malposition of correction ocular to such people.
The inventive method that is used to the people of non-aging eye to make lens especially comprises the following methods step:
In first step, provide the profile of the lens that is ready to wear.What " profile " not necessarily represented explanation is the global shape on the border of lens.The vertical height that lens is described is also enough together with grinding height and other, can fully accurately determine the net shape on border from this explanation." be ready to wear " the expression lens external margin, be that profile no longer changes because lens be polished put in picture frame or because in the situation that no-frame glasses be made into for leg of spectacles is installed.Lens needn't exist with concrete form at this, or rather, knows that the size of lens and outer shape are just enough.This can carry out in the following way, and namely basis is determined the profile of lens and established data thus is provided by the size of the spectacle-frame of this people (glasses are this people's customization) selection.
Be alternative in or be additional to the profile of the lens that is ready to wear, can provide the people for nearby one or more visual tasks and pass one or more (virtual) observation point of the lens that is ready to wear.The determining and can for example carry out in the following way of these joints, namely this people is not in the situation that use lens or utilize its suitable single vision lenses is worn the picture frame of being selected by this people and is required to observe nearby object.Preferably select one or more operating positions, this people will use described glasses usually under described operating position.Then can for example take this people with camera style by means of video camera.Then by means of suitable image analysis method, can determine that sight line passes the joint of lens, this people passes this joint when the visual task of correspondence.Therefore, be arranged on lens or lens and from object arrive that amphiblestroid light passes have a few and all be suitable as observation point.
Then, set place or position, stretching, extension and/or the optical effect (comprising size and distribution) for the zone that reduces the optical effect that vision pressure arranges of should having on lens according to the profile that provides and/or the observation point that provides.In other words, set at least one structure reference point and/or the stretching, extension in described zone and/or the optical effect in described zone in described zone." structure reference point " should be interpreted as point on point on the face of the lens of making or the half-finished face of completing processing of lens according to DIN EN ISO 13666-5.12, and there is the ratings of dioptric effect in the place according to the explanation of manufacturer at this point.
Then based on this information in case of necessity in the situation that further consider prescription values, made the lens with described zone with the promising optical effect that reduces vision pressure and arrange.
in this lens of making, on the one hand for the vertical height in the zone of nearby the measure that reduces vision pressure unlike it is said in the traditional eyewear sheet of the effect that reduces vision pressure and to mate with the demand of eyeglasses wearer consistently like that having, described traditional eyewear sheet has the near-sighted part irrelevant with picture frame type, on the other hand for the size of nearby the measure that reduces vision pressure individually with the demand coupling of eyeglasses wearer, and it is said in the obtainable lens so far of the effect that reduces vision pressure that size and effect are fixing given in advance all the time having.
The optical effect that arranges in order to reduce vision pressure can as above describe in detail comprises prismatic action like that.According to the present invention, can stipulate for this situation, at least one in described structure reference point is to build reference point for the prism of the prismatic action that arranges in order to reduce vision pressure, and sets separately according to the profile that provides and/or the observation point that provides position and/or the stretching, extension of prismatic action and/or the intensity of prismatic action that described prism builds reference point.In other words, the measure of support assembling is arranged in lens individually according to picture frame data and centering data, and according to glasses user's independent requirement the height of the stretching, extension of described measure-especially described measure-and the optical effect of described measure aspect described measure is designed.Therefore the advantage of this modification is significantly, namely supports the measure of convergence and user's demand to mate best.Therefore the erroneous matching of vision pressure or the inefficiency to a great extent of having a mind to the vision support have been avoided producing.
Be alternatively to or be additional to assemble and support, the optical effect that arranges in order to reduce vision pressure can also comprise the effect that near-sighted adjection (Nahzusatzwirkung) or support are regulated as described in equally in the above.According to the present invention, can stipulate for this situation, at least one in described structure reference point is to build reference point for the myopia of the near-sighted adjection that arranges in order to reduce vision pressure or adjection (Addtion), and sets separately according to the profile that provides and/or the observation point that provides position and/or the stretching, extension of described near-sighted adjection and/or the intensity of described near-sighted adjection that described myopia builds reference point.In other words, the measure of support regulating be arranged on individually in lens according to picture frame data and centering data and according to glasses user's requirement the height of the stretching, extension of described measure-especially described measure-and the optical effect of described measure aspect described measure is designed.The advantage of this modification is, supports the measure of adjusting and user's demand to mate best.The erroneous matching of vision pressure or the inefficiency to a great extent of having a mind to the vision support have also been avoided producing at this.
The lens of the present invention that is used for non-presbyopic people comprises that at least one is with the zone of the promising optical effect that reduces vision pressure and arrange.Described lens in principle or conceptive be zero degree eyeglass or single vision lenses, this zero degree eyeglass or single vision lenses have eyeglasses wearer the routine of lens with the time by its geometric areas, optical effect and zero degree effect or spherical and/or toroid and/or the prismatic action of enjoining are different in this geometric areas.The zero degree eyeglass is specific set during for twenty-twenty people at this lens.Single vision lenses is to use when eyeglasses wearer has visual impairment.Have for the geometric areas that reduces the optical effect that vision pressure arranges or zone are configured to near-sighted part under DIN EN ISO 13666-14.1.3 meaning usually, namely be configured to multifocal ophthalmic lens or Zoom glasses sheet for seeing the part that designs nearby.According to the present invention, at least one of described zone builds the stretching, extension in reference point and/or described zone and/or the optical effect described zone in pass this lens that is ready to wear individually for nearby one or more visual tasks with the profile of the lens that is ready to wear and/or corresponding people one or more observation point and mates.
Comprise in the lens of prismatic action for reducing the optical effect that vision pressure arranges therein, the present invention has stipulated such possibility, be that at least one in described structure reference point is for for the prism that reduces the prismatic action that vision pressure arranges builds reference point, and set separately according to the profile that provides and/or the observation point that provides position and/or the stretching, extension of prismatic action and/or the intensity of prismatic action that prism builds reference point.The characteristics of this lens are to support the measure of convergence and user's demand to mate best.Eliminated lens generation vision pressure erroneous matching or have a mind to the inefficiency to a great extent that vision supports.

Embodiment
Fig. 1 illustrates and is used to non-presbyopic people to make the embodiment of the inventive method of lens, and this lens has at least one with the zone of the promising optical effect that reduces vision pressure and arrange.
Can (as long as show need with regard to) in first step 100 one of non-presbyopic people or two eyes be reflected measurement.(Latin language: re=backward for concept " (axially) refraction (Regraktion) ", frangere=fractures) diopter of expression optical correction in optometry and ophthalmology, specific eyes utilize described refraction in the situation that there is no to regulate the picture rich in detail that produces the object that is positioned at unlimited distance.If this diopter is zero, be called twenty-twenty vision or positive eyesight, otherwise be called negative eyesight.
To and need to distinguish about the image definition inquiry those who are investigated's that discover subjective refraction the objective refraction of measuring by means of apparatus.
The measured value of determining when carrying out refraction is transferred to prescription of spectacles in further step 200 in, so-called doctor's advice, this prescription of spectacles for the optist for the manufacture of lens.Myopia and long sight utilize so-called spherical eyeglass lens to be corrected, and astigmatism utilizes cylindrical eyeglass lens to be corrected.In addition, the malposition of one or two eyes may need prism to correct.
In next step 300, eyeglass wearer is preferably selected suitable eye glass frame under optist's assistance.Concept " eye glass frame " can understood under wide significance at this very much.It also can comprise so-called rimless eyeglasses frame, in the situation that this rimless eyeglasses frame, lens only be connected to each other by contact pin and ear-hang or brain after bandage directly be fixed on lens.
According to selected eye glass frame, can directly draw the exterior contour of the lens that is ready to wear from the shape of picture frame.In the situation that the no-frame glasses picture frame, eyeglass wearer still can be with certain restriction exterior contour given in advance.The purpose of step 400 subsequently is, determined the profile of the lens that is ready to wear by the eye glass frame of expectation.
In next method step 500, then determine preferred service condition, the eyeglasses wearer intention following under this service condition is worn this glasses.This is important because draw thus lens with lower area, namely eyeglasses wearer will be extremely possibly by this zone.The method step 500 can selected eye glass frame (step 300) before, because specific picture frame type is not suitable for the condition of wearing of planning, because these picture frame types have limited the ken in unacceptable mode.Also possible is that following eyeglasses wearer may not only be used for unique specific purpose with glasses, but is used for different activities.In this case, determine a plurality of service conditions and in case of necessity for the expection frequency described a plurality of service conditions are weighted.
In next step 600, following eyeglasses wearer faces for the typical visual task of selected service condition.This can for example carry out in the following way, and namely the measured does not use lens by the picture frame of its selection and the paper of reading the newspaper in the situation that common use location is worn on.At this, take its expression with video camera.Then determine pupil position with respect to picture frame according to the shooting of video camera by means of suitable image analysis program.Then thus can the reconstruct sight line from object by the trend of picture frame to eyes.Then can derive sight line by the joint of lens in next step 700.Concept " joint " this should be interpreted as under wide significance in the lens that imagination ground adopts in picture frame or the front of this lens or the position on the back side, pass this position for the sight line of corresponding visual task.The present invention's regulation is studied in case of necessity a plurality of visual tasks and determines corresponding joint, as long as this situation is (step 800) expectation or that need.
Fig. 2 exemplarily is illustrated in the situation of the lens 290 with circular contour 295 when different visual tasks the determining of the joint of sight line, described different visual task such as a) read and write b) are worked before screen, and c) mechanical erection.
In first step, the object that use, be paper or the newspaper 210, situation b of situation under a)) under screen 220 or situation c) under installation wall 230 be introduced in corresponding comfortable position for the user.In second step, determine to pass lens 290 to the corresponding joint 240,250 of object 210,220,230 sight line 270,260 position, for example as described previously from user's eyes 280.
This joint 240,250,260 according to special task a), b), c) and object 210,220,230 apart from the distance of eyes 280 and in lens 290 or high or low.Selected task is lower with respect to eye-level, the joint 240,250 in lens 290,260 lower.Selected task is higher with respect to eye-level, the joint 240,250 in lens 290,260 higher.
Then, according to the profile 295 of lens 290 and one or in case of necessity a plurality of determined joints 240,250,260 can determine that (one or more) are applicable to reduce the measure (step 900) of vision pressure.The measure that can consider in principle to support the measure of regulating or support to assemble or the two.
Then in next step 1000, be set in and realized that wherein (one or more) reduce one or more (inquiry 1100) zone of the measure of vision pressure.Especially possible is, the position of the optical effect be used to reducing vision pressure given in advance, stretching, extension and intensity.
Exemplarily, set forth the setting in zone according to Fig. 3 and 4 below and for the measure that reduces vision pressure of different visual tasks and different picture frame types.From Fig. 3 learn for lens 290 sight lines 270 that have shown in figure 2 circular picture frame type 295 from eyes 280 to object 210,220,230 trend.As top described in detail, corresponding joint according to special task and object 210,220,230 apart from the distance of eyes 280 and in lens 290 or high or low.Similarly, the required support measure regulating and/or assemble is according to special task and object 210,220,230 either large or small apart from the distance of eyes 280.Selected task is lower with respect to eye-level, and the joint in lens 290 is lower.Selected task is higher with respect to eye-level, and the joint in lens 290 is higher.Object 210,220,230 nearer apart from eyes 280, the required support measure regulating and/or assemble is larger, and object 210,220,230 far away apart from eyes, and the required support measure regulating and/or assemble is less.
In the situation of the visual task (read, write) shown in a), observed object 210 is closer apart from eyes 280, namely apart from the about 30-40cm of eyes at Fig. 3.Paper when writing or newspaper be held lower when reading.Determined, sight line 270 be passed in here for the joint of circular lens 290 (representing with Reference numeral 240 in a) at Fig. 2) lower, namely build reference point (Fernkonstruktionsbezugspunkt) 297 far below long sight, it is point on the lens front according to DIN EN ISO 13666-5.15 that this long sight builds reference point, must reach the dioptric effect for the long sight part at this some place.
Suppose according to Fig. 3 example a), the structure reference point 245 of---namely support to regulate with the measure of supporting to assemble---is consistent with the observation point 240 for illustrated visual task for two kinds of measures that reduce vision pressure discussed herein, and is positioned on the front of lens face.In principle, point 245 also can differently be selected with this custom, namely for example is separated from each other on the space and/or on the back side of lens.Therefore be point on lens 290 fronts in the present embodiment for the structure reference point 245 of the measure that reduces vision pressure, must reach at this some place for the dioptric effect of supporting to regulate and support the measure assembled.This structure reference point 245 must be positioned at the profile of the lens 290 that is ready to wear.Because newspaper or paper 210 are arranged very closely apart from observer's eyes 280, support to regulate with the measure (showing by direction arrow 247) of supporting to assemble must be larger aspect their optical effect.The stretching, extension in the zone that the measure with supporting to assemble of support regulating in addition, should be worked therein must be larger.The representative value of the prismatic action of the measure that support is regulated is every 0.25cm/m to 3cm/m Base In (Basis innen) at this.The representative value of the near-sighted adjection of the measure that support is regulated is 0.25dpt to 1.00dpt at this.That support to assemble depends on the measure of supporting the to regulate stretching, extension in the section zone of working within it the design rule of being set by Optical Instrument Designing teacher.Described stretching, extension can be several millimeters of diametrically or also comprise one centimetre or several centimetres.
In the situation that Fig. 3 b) visual task (screen work) shown in, observed object, be screen 220 in the situation that similar apart from the distance of observer's eyes 280 according to Fig. 3 visual task a), namely be in the spacing of about 50-80cm.Only be used for the situation of screen work for glasses, can select unanimously with the observation point 250 for this visual task again for the structure reference point 255 with the measure of supporting to regulate of supporting to assemble.If glasses both have been used for screen work and also have been used for read and write, also can choice arrangement for the observation point of read/write and for the point between the observation point of screen viewing (preferably on the front at lens).Certainly, also can select different structure reference points for the measure with supporting adjusting of supporting to assemble.At last also possibly, on the one hand for the measure that reduces vision pressure of read/write and be selected as in position being separated from each other for the measure that reduces vision pressure of screen work on the other hand and/or its use be selected as varying strength and/or be selected as Bu Tong big or small on it stretches.Be used for reducing the typical regional diameter of measure of vision pressure in the situation that Fig. 3 b) depend on design as top having shown.Can get again value between 0.25cm/m to 3cm/m for the possible prismatic action of the measure of support assembling.Support the near-sighted adjection that may use of the measure of adjusting to be in about 0.25dpt to 1.0dpt.Reduce the optical effect (prism and adjection) of the measure of vision pressure at Fig. 3 b) in direction arrow 257 sign.
In the situation that Fig. 3 c) visual task (installation) shown in, observed object 230 has the spacing of 30-40cm apart from observer's eyes 280, but same high with eyes 280.For this situation, can be selected as equally consistent with observation point 260 for the structure reference point 265 of the measure that reduces vision pressure.For this visual task, be in about 0.25cm/m to 3cm/m for the typical prismatic action of the measure of support assembling, typical adjection is in about 0.25dpt to 1.0dpt, and regional diameter also depends on design at this.Reduce the optical effect (prism and adjection) of the measure of vision pressure at Fig. 3 c) in represent with direction arrow 267.
According to the profile of lens shape or according to the height of this profile, so locate in lens 290 in structure reference point or zone that support must be regulated and/or the measure that support is assembled, make it corresponding with the situation of activity on the one hand, but also still be positioned at picture frame profile 295.Fig. 4 illustrates corresponding characteristic with Fig. 3 with comparing, namely for identical service condition---read/write (Fig. 4 a), screen work (Fig. 4 b) and install (Fig. 4 is a)---for the measure that reduces visual fatigue 347,357 of the situation of the lens 390 with rectangle picture frame type 395,367 intensity and build reference point 345,355 and 365.
Fig. 5 have similar elliptic contour 495,595 but the lens 490 of different sizes, 590 and have rectangular shape 695 lens 690 unite shown in demonstration representational structure reference point 445,545,645 for the visual task read/write.
The structure reference point of describing before be based on and other is for calculating the common data of lens---as refraction, material and service condition, can make the lens (step 1200) of the mode according to the present invention.
